This crawl started in April 2019, as an informal collaboration with Crossref. Crawling a smallish number (100k) DOI redirects and landing pages (plus PDF outlinks, and maybe a couple other hops) for a single large publisher (OMICS, which has multiple subsidiaries). Intent is to get reasonably good capture that can be used as canonical preservation copies of the landing pages. Secondary goal is to get decent fulltext capture coverage.

This collection contains web crawl data for a random selection of 500k (0.5 million) Crossref DOI redirects, including the doi.org redirect requests. The intent of this crawl is to gather loose statistics on the number of failing redirects, number of host websites that block automated crawling, and a corpus of HTML landing pages for metadata extraction (eg, "signposting" HTTP headers, linked data HTML metadata, semantic markup). Total size of (uncompressed) WARC data is 50 GB,...

This collection holds database snapshots (SQL) and bulk metadata exports (JSON and TSV) from https:///fatcat.wiki (an Internet Archive service)
This item contains a complete PostgreSQL SQL database snapshot from https://fatcat.wiki, in binary 'pg_dump tar mode' format. With the exception of the 'abstracts' table (for which no aggregate license or copyright claims can be made; downstream users are responsible for their use), all metadata here is licensed CC-0 (public domain release) and may be used for any purpose. Downstream users are strongly encouraged to provide attribution and link here to the snapshot, as well as give credit to...
This is a mapping between: - DOIs (Crossref) - PubMed PMID and PMCID (NIH) - CORE record identifier (core.ac.uk) - Wikidata QIDs See README and scripts for details.

This item contains re-compiled .jar files for JVM (Java, Scala, etc) software packages used by the archive's "sandcrawler" journal ingest pipeline.
This item contains hash lists of PDF files crawled from the public web specifically to preserve the scholarly record. It does not contain hashes of *all* PDFs the archive has ever seen, only a subset. Not all of these hashes are necessarily journal articles or other research outputs, but we have reason to believe the large majority are.
Contains a TSV file with SHA1, file size, wayback URLs, and metadata extracted from PDF by GROBID. Not intended for external use, but might be interested. DOES NOT CONTAIN FULLTEXT CONTENT.

This item contains an example corpus of citations between scholarly documents, as extracted from the fatcat (https://fatcat.wiki) corpus as of the 2020-08-05 bulk release export. This corpus itself was generated from a fatcat-scholar "intermediate" fulltext dump which is not public, using software in the fatcat-scholar repository in mid-September 2020. See also the README for some more notes, and the "sample" file.

This item contains a copy of log files found on the Internet Archive (Web Group) machine `wbgrp-svc263.us.archive.org` on 2018-05-29, under the `/3` directory. These are logs of file transfer status between various crawler machines; they are not known to contain any sensitive metadata (eg, personal information, IPs, or other security-sensitive information), but are being keep `access-restricted` anyways. This data is almost certainly unimportant and could be deleted; it is being preserved out...

Test runs of large-scale matching algorithms (sha1 to DOI). Will likely be obsolete soon, and not useful for others.

This item contains datasets of homepage URLs found by hand using search engines and bibliographic metadata (eg, ISSN and journal title). The "long-tail" batch contains about 4,600 journal lookup results, with about 3,900 successful homepage URLs found. The list of journals was created in May 2020, and the lookup work completed in June 2020. IA staff member Richard Greydanus ran this batch of lookups. All of this metadata can be considered public domain, or CC-0 (Creative Commons Zero)...
A mirror of the Unpaywall (aka oaDOI.org) metadata corpus, primarily consisting of public open access flags for a large number of Crossref-registered DOIs (identifiers representing published journal articles and other works). For more information see: http://unpaywall.org/products/snapshot
Data-munged title-level metadata combined from: DOAJ, ROAD, Norwegian Register, and Internet Archive crawled metadata. See SOURCES.md for URLs of upstream metadata, and ISSN_matching.html for Jupyter notebook used to derive this dataset.
This item contains sqlite3 database snapshots, URL crawl status, and other metadata useful for doing analytics on journal OA coverage, homepage status, etc. Particularly in the context of https://fatcat.wiki. Source code: https://github.com/bnewbold/chocula
See also the crawl logs item for this crawl.
